I bought that file earlier this year and its got some issues.
The first pic shows the errors that keep this from being printed without repair. When I put it in Lychee slicer, most of the body didn't even show as printable.
The other pics show where I cut the front end from the file and added it to the Beetle body I have from parting out the kit for my Peking to Paris Karmann Ghia.
I cut the front end off in Meshmixer and did a lot of resizing and reprinting to get it right. I'll do the rear when I decide to build it.
That might be an option for you as well using the full kit.
